Used to enable or disable nested parallelism.
SUBROUTINE OMP_SET_NESTED(scalar_logical_expression)
#include <omp.h>
void omp_set_nested(int nested)
For Fortran, calling this function with .FALSE. will disable nested parallelism, and calling with .TRUE. will enable it.
For C/C++, if nested evaluates to non-zero, nested parallelism is enabled; otherwise it is disabled.
The default is for nested parallelism to be disabled.
This call has precedence over the OMP_NESTED environment variable
